PREVALENCE AND CHARACTERISTICS OF DENGUE VIRUS SEROTYPES IN GOIÁS

Abstract

This study analyzed the prevalence of dengue virus serotypes in the state of Goiás, Brazil, between 2014 and April 2024, based on data from the Notifiable Diseases Information System (SINAN). The research aimed to understand the distribution of serotypes DEN 1, DEN 2, DEN 3, and DEN 4, in addition to evaluating their evolution over time. A quantitative methodological approach was used, with analysis of secondary data and preparation of graphs using tools such as Microsoft Excel and Word. The study found that, of 16,715,715 reported cases, only 1.75% had serotype specification, with serotype DEN 2 being the most prevalent (54.77%), followed by DEN 1 (42.71%). DEN 3 had the lowest frequency, with 0.12%, and DEN 4 represented 2.38% of cases. The predominance of DEN 2, especially in the last two years, suggests a relationship with population immunity and may be associated with increased virulence. The study concludes that epidemiological surveillance and serotype typing are essential for the development of effective dengue control strategies, considering the local characteristics of each region.
